Improvement of efficiency on the generation side

	Combined heat and power modules
An advanced gas-driven combined heat and power module generates both heat and  power simultaneously in one. In this process, a combustion engine drives an electric generator, and the generated power is fed directly into the on-site network. The waste heat from the engine and the heat from the exhaust gas are used via a heat exchanger to heat the building. The CHP module can operate with natural gas or biogas.   Power generation: 1 335 MWh p.a. CO2 reduction: 320 t p.a.
	Condensing technology
Condensing systems sustainably increase efficiency when generating heat from gas and oil. The basis for this lies in yielding additional heating energy from the flue gas. Because of the high demands condensing technology makes of materials, heating surfaces are made from high grade stainless steel. Highly efficient compact condensing boilers deliver a seasonal efficiency [to DIN] of up to 98 percent. These are also designed for a proportional use of biogas.   Energy savings in natural gas: 1 108 MWh p.a. CO2 reduction: 165 t p.a.
	Flue gas/water heat exchangers for industrial/commercial boilers
Industrial/commercial boilers operated with either oil or gas are equipped to utilise condensing technology with flue gas/water heat exchangers. These cool down the flue gas temperatures so that water vapours condense. This releases latent heat, and the low flue gas temperatures ensure an increase in efficiency [to DIN] of up to 12 percent.
